Lennox HVAC in Atlanta, CA | Brandt HVAC
We provide independent Lennox HVAC service across Atlanta, and the one thing that makes our Lennox work here different is simple: we know which parts fail on which models during Atlanta’s hard freezes and pollen seasons, and we stock for those failures before they happen. We’re not a Lennox factory dealer or authorized contractor. We’re an independent Lennox service provider led by Devin Marlowe, and we’ve spent years repairing Lennox heat pumps, air conditioners, and furnaces across Atlanta’s intown bungalows and suburban tract-home belt. Call (984) 538-9003 for a free estimate on any Lennox repair, maintenance, or replacement.
If you need broader Lennox sales & service information or want to see our full Atlanta service area, those pages cover the basics. This page goes deeper: Atlanta-specific Lennox failure patterns, honest pricing, and what we do differently when your system fails on the worst possible day.
Why Atlanta Residents Choose Us for Lennox Service
Devin Marlowe grew up in the San Fernando Valley, earned his HVAC/R training at Los Angeles Trade-Technical College, and has spent nearly two decades diagnosing heating and cooling problems before settling into this work. That hands-on foundation shows in how we approach every Lennox system we touch. We trace the problem to the component, not the sales pitch.
Atlanta’s housing stock runs the full range: 1920s Craftsman bungalows in Grant Park and Kirkwood with crawl spaces and ductwork never designed for central air, and a vast 1980s to 2000s suburban tract-home belt across Gwinnett, Cobb, Cherokee, and Forsyth counties where builder-grade heat pumps are now hitting their 20-to-25-year replacement window. We service Lennox systems in both. Our techs carry Lennox-specific parts that fail most in Atlanta: defrost control boards, strip-heat sequencers, reversing valves, drain float switches, and the capacitors that Atlanta’s humid heat kills early. Every technician who arrives at your door is background-checked, uniformed, and introduced to you by name and photo before the visit under the Threshold Verified standard. If anyone shows up who you weren’t told to expect, that visit is on us.
Common Lennox HVAC Problems We Solve in Atlanta
- Frozen outdoor coils and failed auxiliary strip-heat on Merit and Elite heat pumps during hard freezes. Atlanta’s 2014 and 2021 ice events dropped temperatures into the teens and froze up thousands of Lennox 14HPX, ML14XP1, XP14, and XP16 units in a single night. The defrost board, reversing valve, and crankcase heater are the usual casualties. A heat pump that can’t defrost will blow cold air while the strip heat struggles or trips entirely.
- Pine and oak pollen packing the condenser coil every spring. Atlanta has the densest tree canopy of any major U.S. city, and the annual pollen surge coats Lennox XC14 and XP14 condenser coils in a thick yellow film. The coil can’t reject heat, head pressure climbs, and the compressor overloads. We recommend a dedicated coil cleaning every spring, not as an add-on but as necessary maintenance for Atlanta Lennox owners.
- Clogged condensate drain lines and tripped safety float switches. Atlanta’s humid subtropical summers push dew points above 70°F, so your Lennox system pulls gallons of water from the air daily. On 1980s to 2000s builder-grade Lennox equipment now 20 to 25 years old, drain lines clog with algae and the float switch kills the system to prevent water damage. Then you’re left with a dead AC on a 90-degree day.
- Cracked heat exchangers in older Lennox furnaces. We still see G40, G50, and early EL series furnaces in intown Atlanta crawl spaces where rettrofitted ductwork chokes airflow. Decades of cycling under marginal airflow stresses the heat exchanger until it fails. If you have an older Lennox furnace in Grant Park or Kirkwood, this is worth checking before winter.
- Failed ignitors and gas valves on 15-to-25-year-old Lennox furnaces. These components wear out on a predictable schedule in Atlanta because our winters, while mild, still cycle furnaces enough to accumulate wear. Most ignitor replacements run $175 to $300, parts and labor included, with a written guarantee.
Lennox Service in Atlanta: What Local Conditions Mean for Your Equipment
Atlanta sits at a climate threshold that most of the country doesn’t understand. Our winters are mild enough that heat pumps dominate the residential market, so the install base is overwhelmingly Lennox heat pumps rather than gas furnaces. But when a hard freeze or ice storm hits, every heat pump in the metro tries to defrost at once. The auxiliary strip heat that’s supposed to carry the heating load kicks on, and systems that have never been stressed suddenly fail. After the 2021 ice storm, we had a 12-year-old Lennox XP14 heat pump in Grant Park stuck in defrost with the auxiliary strip heat tripped, leaving the house at 54°F. Our tech replaced the failed defrost control board and a blown 60-amp sequencer, cleared the frozen condensate line, and had the system heating normally within two hours. The same week we did the same repair on three other Lennox heat pumps across Kirkwood and Virginia-Highland, all with the same freeze-related control-board failure. No warm-climate market sees this kind of storm-driven demand spike. That’s why we pre-stage defrost boards and strip-heat sequencers before every forecast Atlanta freeze, so we can triage the backlog instead of waiting on parts.
Lennox Models & Products We Service in Atlanta
We work on the full Lennox residential lineup. That includes the Merit Series (14HPX and ML14XP1 heat pumps, 13ACX AC condensers), Elite Series (XC14 and XC16 air conditioners, XP14 and XP16 heat pumps), Dave Lennox Signature Collection (XC21 and XC25 AC, XP21 and XP25 heat pumps), and Lennox furnaces including the SL280V, EL280, and EL296V. We also service Lennox mini-split lines including the MS8, MPA, and MLA. For critical components like defrost boards, reversing valves, control boards, ignitors, gas valves, and heat exchangers, we use OEM Lennox parts so the repair holds up and your system keeps its rated efficiency. For generic items like capacitors and filters, we use quality aftermarket equivalents and tell you which is which. We keep common Lennox parts stocked locally for fast Atlanta turnaround, which matters when your heat pump is frozen on a January morning.

FAQs – Lennox HVAC in Atlanta
Your defrost control board, reversing valve, or crankcase heater has likely failed, so the heat pump can’t cycle out of defrost mode. When temperatures drop into the teens like they did in 2014 and 2021, even healthy Lennox heat pumps ice over, but a failed defrost component leaves you with no heat at all. This is the most common freeze-related failure we see on Merit and Elite series heat pumps in Atlanta. Call (984) 538-9003 and we’ll diagnose it same day.
Two things usually: the condenser coil is packed with spring pollen and can’t reject heat, or the system is undersized for Atlanta’s dehumidification load, which is as significant as the sensible cooling load here. A clogged drain line can also trip the float switch and shut the system down entirely. We’ll clean the coil, clear the drain, and tell you honestly if the problem is mechanical or a sizing issue.
Once a year, in spring, after the pine and oak pollen surge. Atlanta’s tree canopy produces pollen so heavy it packs coils in thick yellow film within weeks. A coil that isn’t cleaned every spring runs high head pressure, which shortens the compressor life on Lennox XC14 and XP14 units specifically. Our tune-up including coil cleaning and drain flush runs $80 to $200.
Usually not. A 20-to-25-year-old builder-grade Lennox heat pump has outlived its designed service life, and putting a $400 defrost board into a system that may fail again next season is throwing good money after bad. We’ll tell you that directly, with a written replacement quote if you want one. That’s the honest answer we give every Atlanta homeowner.
Yes. For all critical components including heat exchangers, ignitors, gas valves, defrost boards, and reversing valves, we use OEM Lennox parts. For generic parts like capacitors and filters, we use quality aftermarket equivalents and tell you upfront which is which. Every repair includes a written guarantee, and if it fails within 365 days, we return at no charge under the 365-Day Done Right Promise.
